Outline of Final Research Achievements |
The most important task in the field of atomic structures is currently to experimentally obtain structures around light elements. In the present project, we tried to develop holography technique that enables one to draw three-dimensional atomic images without any special model, to investigate local structures around light elements with the same accuracy as those around heavy elements. We have succeeded in detecting fluorescent photons of Al etc. with enough counts for holographic experiments by utilizing a curved mirror. We will try to visually understand the relationship between atomic structures and properties in functional materials containing light elements.

Academic Significance and Societal Importance of the Research Achievements |
散乱やXAFSでは容易には得る事ができない、軽元素のまわりの局所原子配列を、重元素のまわりとは遜色のない精度で検出することが可能になった。この開発研究により、ワイド・ギャップ半導体など、軽元素が重要な機能性材料を対象として、軽元素のまわりの格子ひずみやクラスター形成など、材料の3次元的特徴を描き出し、物性との関連を明らかにする。その結果は、さらに高度な機能を発現する材料の開発など、産業面に大きなインパクトを与える。
